Q I cannot hear any sound while watching.

A If there is "V_ONLY" shown above the image, click on connection type to uncheck "Disable audio". If there is "V" shown instead of "AV", the sound card in your PC may not have been properly installed. If "AV" is shown, check the audio source of the network camera, and make sure of whether you are using an internal or external microphone.

Q How many users are allowed to watch the network camera at the same time?

A Too many users requesting the real-time multimedia content will jam the network. For best results, the network camera is designed to accommodate a maximum of ten (10) users to watch and listen at the same time. For a larger number of users, it is recommended to build another web server to host the retrieved content from the network camera.

Q How fast is the video rate of the network camera?

A The MPEG-4 codec engine can process up to 30 frames per second internally. However, the total performance is subject to many coefficients such as:

1.Network throughput

2.Bandwidth sharing

3.Number of users

4.The complicated/detailed objects and movement in view

5.The power of your PC or notebook computer that is responsible for displaying images.

On average, the transfer rate in a general local network environment can reach over 200 kilobytes per second and approximately 10 to 20 pictures per second from a regular environment.

Q How can I keep the network camera as private as possible?

A The network camera is designed for surveillance purposes and has many flexible interfaces. The user authentication and special confirmation in installation can keep the network camera from unauthorized access. You may also change the HTTP port to a non-public number. The demo account is good to separate guests from normal users, and thus, you can easily block the guests anytime. You can check the system log to examine any abnormal activities and trace the origins.

Q Why can I not access the network camera when I set up some options in the application?

A Any incorrect network settings will make the network camera inaccessible. If this happens, restore the factory default settings following the procedures in Appendix A.
